Energy Harvesting from Human Locomotion using Piezoelectric Transducer-Based Shoe

In this paper a proposed design of a piezoelectric transducer-based energy harvesting device has been presented. The primary goal of the research was to develop a device that can charge up the batteries of smartphones or other small-scale gadgets using the energy from human locomotion. The operation of our charging device involves the conversion of the mechanical stress produced in the transducer plates by human footsteps during walking, sprinting, etc. into alternating current and voltage which is then rectified and adjusted by electronic circuit combinations to meet the direct current and voltage requirements for replenishing the battery charge.
